A Knight’s Tour.

Sixty-four steps.
One surprising number.

Number each square as the knight visits it. In William Beverley’s 1848 tour, every row and every column adds up to 260.

It’s a semi-magic square: the diagonals don’t share that total. A fully magic knight’s tour is impossible on an 8 × 8 board—but this is a beautiful near miss.
